摘要
应用有限单元法对桁架结构进行了分析、计算。从桁架的用途、实际使用环境概括了桁架计算的边界条件;根据设计图纸和实际工况选择一维单元建立了桁架的有限单元模型;在有限单元模型上加载边界条件,根据线性理论解算得出计算结果,并且根据计算结果对设计进行评估,结合以往设计总结出桁架结构设计的一种有效分析、计算方法。
Finite element method is applied to design and calculation of the trusswork in this paper. Boundary conditions is summed up ~om the purpose and actual work situation of the tmsswork; finite element model of the trusswork is built by one dimension element chose according to the drawing and actual condition. With boundary conditions finite element model has obtained its result according to linearity theory. After FEA results are carefully analyzed, relating to the experience, a available method of analysis and calculation is summarized for the design of the trusswork.
